INVBNTOR KLAUS MAYER lf ATTORNEYS United States Patent 3,613,286 REVOLVER WITH DOUBLE ACTION Klaus Mayer, 9 Arnsberger Strasse, Neheim-Husten, Germany Filed Apr. 16, 1969, Ser. No. 816,656 Int. Cl. F4lc 19/00 US. Cl. 42-65 2 Claims ABSTRACT OF THE DISCLGSURE A revolver with double action is characterized in that the actuating part is shaped as a flat tension slide. This slide is guided in a straight movement along an end edge of the casing to the firing pin. The slide has teeth upon its lower side which mesh with a gear segment of an operational member of the firing mechanism.

This invention refers to a revolver with double action. The invention is particularly concerned with a revolver wherein the required actuation of the firing mechanism to produce a shot or several shots following each other takes place by operating a trigger. However, to produce a well aimed single shot, it is possible to cock the firearm by means of a hammer and then release it by a considerably small movement of the trigger. For that purpose, in existing revolver constructions, the hammer used to ignite the cartridge projects out of the firing mechanism above the handle and can be moved by the thumb out of the front rest position to the cocking position ready for firing. To provide a sufficient engaging surface for the thumb of the hand holding the handle and to assure a secure swing actuation into the cocking position, a part of the hammer clearly projects out of the handle as an actuating lug.

On the other hand, these operational requirements have the drawback that the use of the firearm is made difficult. Thus there is the danger that the revolver with its hammer or lug will be caught in the lining of the coat pocket or the trouser pocket of the user, thereby preventing the quick pulling of the firearm. In addition, the actuating lug of the hammer makes difficult the use of the revolver while it is inside the pocket.

Attempts have been made to avoid these difiiculties by enclosing the hammer in a special cover which does not interfere with its swinging movement but keeps it enclosed to a great extent during its swinging movement up to a corrugated engaging surface. This auxiliary construction prevents, to a great extent, the possibility that the hammer will be caught in the clothes lining. However, this construction reduces the operational safety by diminishing the engageable length of the lever arm to a small surface extending outside the cover. The size of the firearm is also increased. Furthermore, this hammer cover cannot be used in tip type revolvers wherein the firing mechanism is provided in the rear section of the view finder.

An object of the present invention is to construct a revolver the firing mechanism of which will not have the drawbacks of existing hammer construction without using, however, any separate parts for that purpose.

Other objects of the present invention wil become apparent in the course of the following specification.

In carrying out the objects of the present invention it was found that the portion projecting out of the firing mechanism above the actual handle in the form of a hammer for the manual setting of the firearm is the suitable starting point for a basic constructional improvement.

Consequently, the objectives of the present invention pertaining to a revolver with double action may be realized by shaping the actuating member as a flat tension slide which is guided in a straight movement along an end edge ice of the casing to the firing pin and which has teeth upon its lower side meshing with a gear segment of an operational member of the firing mechanism.

In this manner, by changing the circular tensioning movement into a straight line movement, the present invention results not only in the desired rounding off but also makes possible the construction of a firearm of smaller size, wherein the actuating member follows closely the outline of the casing and does not swing out of it, like the hammer. This has the further result that the revolver can be now cocked by an unobtrusive movement inside a coat pocket and then fired without the danger that the hammer of the present invention will be caught in the lining.

Thus the construction of the present invention solves advantageously the heretofore incompletely solved requirements for a hand-operated firearm with double action.

In accordance with a further advantageous development of the present invention, the slide is mounted on both sides within the frame in a straight fiat guide and extends over an end edge of the casing which is parallel to the guide with the same width as that of the sliding plane by its own corrugated, thumb engaged surface. Due to this construction, the slide is provided with a precise guide within its operational range and at the same time the delicate firing mechanism is protected against the penetration of dirt particles. Due to modern manufacturing methods, the apparent additional costs as compared to prior art hammer covers are of no significance.

Furthermore, the operational member of the firing mechanism which is mounted in the casing and which according to an advantageous embodiment of the present invention has a toothed segment engaging the slide movable along a straight line in the casing, is precisely the same in its further structure and location as the existing construction of a hammer. Thus the present invention retains the rest of the firing mechanism without any changes.

Consequently the present invention provides revolvers which are better than known constructions as far as function and operation are concerned in that they are adapted to the actual operational purpose of such firearms to a much greater extent than has been attained heretofore.

The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings, showing, by way of example only, a preferred embodiment of the inventive idea.

In the drawings:

FIG. 1 is a partial side view of a tip type revolver known in prior art;

FIG. 2 is a top view of the portion of the revolver shown in FIG. 1;

FIG. 3 is a section through a part of a revolver constructed in accordance with the present invention and il lustrates the slide, the firing mechanism and the trigger;

FIG. 4 is a section through the slide and a part of the firing mechanism along the line IVIV of FIG. 3.

The tip type revolver shown in FIGS. 1 and 2 has a casing 1 connected with the handle and containing the firing mechanism. A forwardly tipping part of the revolver which includes the drive and the cylinder 2 is rotatably mounted in the casing 1 and these two parts can be locked in the viewing range by a swing lock 3.

In the revolver of the present invention shown in FIGS. 3 and 4 the prior art hammer is repiaced by a slide 4' which is movable rearwardly in a straight line along the upper end edge of the casing frame 1' so as to cock the firearm by means of its corrugated thumb-engaged surface. For that purpose, the slide 4' is mounted in the casing 1 in a rectangular guide 5. The lower portion of the slide is provided with teeth 6 which mesh with the teeth of a toothed segment of the next operational member 7 of the firing mechanism. This operational member 7 is mounted at 8 in the casing and is precisely the same as far as its form and operation are concerned as the inner member of the prior art hammer construction.

Consequently, as far as the different operational procedures are concerned, such as setting, cocking and firing, it is merely necessary to mention that the slide 4' which is moved by hand into the cocking position is released by the operational member 7 when the trigger 10 is pulled and then is moved along a straight line by spring action to a firing pin 9 which is located in the casing 1' and which thus causes the ignition of a cartridge located in the cylinder 2'. It is apparent that the same procedure will take place without the preliminary cocking of the firearm merely by the pulling of the trigger 10, whereupon the slide 4 will carry out one after the other the above described movements.

The above described construction of the present invention of a hand-operated firearm is superior to prior art revolvers not only operationally, but also by requiring greatly less attention and care for proper operation due to a complete enclosure of the firing mechanism by the corresponding arrangement and construction of the slide.
